NOTE: The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentials in 1500 Model vehicles re-
quire that 4 oz. (118 ml) Mopart limited slip additive be
added to the gear lubricant. Refer to Fluids, Lubricants
and Genuine Parts for correct fluid type. The Mopart
Limited Slip Additive should be added to the gear
lubricant whenever a fluid change is made.
Ram 2500/3500 Model Axles DO NOT REQUIRE any
limited slip oil additive (friction modifiers).
